Transforming old mine shafts into future storage sites

Just as there is an interest in sources of energy, there is also an urgent keen interest in storage. What is viable, as in what can work efficiently and make economic sense?


In the physical sciences, the weight of an object is the magnitude, W, of the force that must be applied to an object in order to support it (i.e. hold it at rest) in a gravitational field. The weight of an object equals the magnitude of the gravitational force acting on the object, less the effect of its buoyancy in any fluid in which it might be immersed. Near the surface of the Earth, the acceleration due to gravity is approximately constant; this means that an object's weight near the surface of the Earth is roughly proportional to its mass.
